I connected an OS7200 PBX with a PRI line. All settings done, the outgoing call is failing to show caller ID and thus other public switches are rejecting through connectivity. they say PBX data should have screen indicator value =3 on the IAM mesage. plz help for there is zero success rate on outgoing calls. Is there a platform where I can view data sent from the TEPRI on the PRI line?
